Convert the legacy TXT binding for the TWL6030 USB module
to the modern YAML DT schema format. This adds formal validation
and improves documentation using a conditional schema.

Changes in v5:
- Split combined twlxxxx-usb binding into a dedicated file for
twl6030-usb per maintainer feedback.
- Used more accurate header for interrupt macros.
- Improved formatting in the examples.
Changes in v4:
- This patch is split from larger series per maintainer feedback.
- v3 link:
https://lore.kernel.org/all/20250816021523.167049-1-jihed.chaibi.dev@xxxxxxxxx/
- Removed i2c node as it wasn't required by the old binding file.
- Updated node names to 'usb' and 'usb-phy' in the examples to follow
generic naming conventions per the Device Tree specification.
- Replaced raw interrupt values with standard defines for clarity.
- Improved formatting in the examples for clarity and consistency.
Changes in v3:
- No changes.
Changes in v2:
- Added '#phy-cells' property to support PHY framework integration.
